Optimize the following rust function without changing its signature and functionality.

Minimize the range of unsafe blocks as much as possible in the function.
Improve the readability of the code.
Rust function:
{rust_code}
Following are static global variable declarations of this module, access and usage of them should be unsafe:
{static_variables}
This is the extern C declaration of this module, other functions except for these are safe:

second_optimize_prompt = """
The following Rust function may define some raw pointers, or the parameters passed in may contain raw pointers.
Before using these pointers in the code, convert them to Box type variables. If the raw pointers involve writing, the Box should be mutable. 
Then convert read and write operations on the raw pointers to operations on the Box variables, minimizing the scope of the unsafe block in the function.
Note that the conversion from raw pointer to Box type should occur after definition, do not modify the definition of the raw pointers.
Before the function returns, convert the Box variables back to raw pointers to prevent the Box from being automatically dropped and to keep the function's return type unchanged.
Ensure that for the same raw pointer, the conversion to Box type and back to the raw pointer is only done once. Do not repeatedly convert.
Rust function:
```rust
{rust_code}
```
Following are other instructions you need to follow:
1. The declaration of static global variables is provided below, and read/write operations on these variables should be unsafe. 
Static Global Variables:
```rust
{static_variables}
```
2. The declaration of extern C functions is provided, and all functions except these are safe. If some called function's parameters are unsafe, use an unsafe block on the parameters instead of the entire function.
If there is error message and tells you which function is unsafe, rely on the error message.
Extern C Functions:
```rust
{extern_C}
```
3. Minimize the scope of the unsafe block in the function.
4. If there are other functions used as parameters in the Rust code, these functions are safe, so you can directly use them without unsafe block:
Origin Code:
```rust
unsafe {{
    tree = avl_tree_new(
        std::mem::transmute::<
            Option<unsafe extern "C" fn(*mut libc::c_void, *mut libc::c_void) -> libc::c_int>,
            AVLTreeCompareFunc,
        >(Some(int_compare)),
    );
    list_remove_data(
            &mut list,
            Some(int_equal as unsafe extern "C" fn(
                *mut libc::c_void,
                *mut libc::c_void,
            ) -> libc::c_int),
            &mut val as *mut libc::c_int as ListValue,
        );
}}
```
Optimized Code:
```rust
tree = avl_tree_new(
        (Some(int_compare)),
    );
list_remove_data(
        &mut list,
        Some(int_equal),
        &mut val as *mut libc::c_int as ListValue,
    );
```
string_equal, pointer_equal, string_compare and pointer_compare are the same:
Some(string_equal), Some(pointer_equal), Some(string_compare) and Some(pointer_compare)
5. Only dereference of raw pointer should be considered unsafe.
6. If there are error message and previous generation, you should fix or avoid the error in new generation.
7. Ensure that the number of `assert` statements remains unchanged, neither increasing nor decreasing.
8. Only convert functions, do not add context. Only output results, no need for explanation.

# parallel_opt_prompt="""
# The following Rust function may involve use of global static variables, whose definitions have been modified:
# Variable `num_assert` is modified using Mutex and lazy_static.
# Other variables are modified using RefCell and thread_local.
# Rust function:
# ```rust
# {rust_code}
# ```
# Modified Global Variables Definitions:
# ```rust
# {static_variables}
# ```
# Make corresponding modifications to their usage in the function based on the above modified definitions following the rules below:
# 1. All operations on the variable `num_assert` must be wrapped in curly braces, for example:
# {{
#     let mut guard = num_assert.lock().unwrap();
#     *guard = guard.wrapping_add(1);
# }}
# 2. Use borrow() to access RefCell variables.
# 3. Use borrow_mut() to modify RefCell variables, for example:
# counter.with(|c| {{
#         let mut counter_mut = c.borrow_mut();
#         unsafe {{
#             assert!(*key > *counter_mut, "*key > counter");
#             *counter_mut = *key;
#         }}
#     }});
# 3. If need raw pointer of a RefCell variable, use `&mut *variable_name.borrow_mut()` to get the raw pointer.
# 4. If varaiables involve dereferencing a raw pointer, it should be enclosed in an `unsafe` block, for example:
# assert_ne!(
#             binomial_heap_insert(
#                 heap,
#                 unsafe {{ &mut *test_array.with(|arr| arr.borrow_mut().as_mut_ptr().offset(i as isize)) as *mut libc::c_int as BinomialHeapValue }},
#             ),
#             0,
#             "binomial_heap_insert(heap, &test_array[i])!= 0"
#         );
# 5. If the code does not contain any variables in Modified Global Variables Definitions, keep the code unchanged.
# Do not modify any part of the code other than these variables.
# Only convert code, do not add context. 
# Only output results, no need for explanation.

Carefully check if the code contains variables mentioned above.
